IRAF contains a Fortran interface called IMFORT which allows users to write their own Fortran programs that read and write data in the IRAF (OIF) image format. The subroutines provided in IMFORT can be called from any Fortran program, and you can run your program independently from IRAF. There is a limited capability for integrating an IMFORT program with IRAF so that the program can be used in conjunction with other IRAF or STSDAS packages without leaving the IRAF CL.
IMFORT supports image I/O to IRAF (OIF) format files only. You cannot read or write GEIS format images or STSDAS tables using this interface.
